在实际创建文件之前查找文件名是否有效
我有一个使用 C++ 构建的 wxWidget 应用程序。该应用程序的功能之一是它提示用户在消息框中输入字符串，然后一旦用户按下 Enter 键，它就会创建一个文件，该文件的名称就是用户输入的字符串数组。
现在我有一个问题，我想检查用户输入的字符串是否可以是有效的名称**。
一种方法是检查该文件是否已在系统上创建，并告诉用户这是一个无效字符串。（我不想这样做）。
另一种方法是解析整个字符串以检查字符串中是否包含无效的文件名字符，例如 <、/、\ 等。
有没有其他方法可以检查这个不涉及任何文件操作？
I have an wxWidget application built using C++. One of the functionalities of the application is that it prompts the user to enter a string in a message box and then once users presses Enter, it creates a file with the name of the file being the string array user entered.
Now I have an issue, I want to check if the string entered by the user can be a valid name or not**.
one way is to check if the file has been created on the system and tell the user it is an invalid string.(I dont want to do this).
another would be to parse the entire string to check if it has invalid file name characters like <, /, \ etc in the string.
Is there any other way I can check this which doesn't involve any file operations?

您可以使用静态函数：
获取与您的字符串匹配的无效字符列表。您可以在此处查看其文档。虽然它不会排除所有无效的文件名，但它可能足以满足您的需求。
You could use the static function:
to get a list of invalid characters to match against your string. You can see its documentation here. Although it wont rule out all invalid filenames, it might be good enough for what you want.
